It's been a busy week for Windows Phone navigation apps. First we see NAVIGON released that brings on-board maps to your Windows Phone to eliminate the need for a data connection for route calculations and maps. Now we see GPSTuner, developer of Outdoor Navigator and Turn by Turn Navigation, release a new version of Turn by Turn that also includes offline maps.
But wait, the original version of Turn by Turn had downloadable maps. True, but the process was a little cumbersome and the original version still required a data connection for routing and for the times you strayed from the map shot you downloaded.
The new version of Turn by Turn Navigation allows you to choose regional maps to eliminate the need for a data connection. This also allows you to minimize storage requirements by allowing you to choose what maps are downloaded. If you never stray from the Western US, why should you tie up storage with East Coast maps?
The app itself has changed very little (you do have a new search function) but the performance is noticeably improved with the addition of on-board, offline maps. To see how Turn by Turn Navigation US + Canada managed the open road, move on past the break.
